G2 Haskell Symbolic Execution Engine


About

G2 performs lazy symbolic execution of Haskell programs to detect state reachability. It is capable of generating assertion failure counterexamples and solving for higher-order functions.


Dependencies


Setup:

  1. Install GHC.
  2. Install Z3. Ensure Z3 is in your system's path.
  3. Pull the Custom Haskell Standard Library into ~/.g2 by running bash base_setup.sh.

Command line:

Reachability:

cabal run G2 ./tests/Samples/Peano.hs add

LiquidHaskell:

cabal run G2LH ./tests/Liquid/Peano.hs add

Arguments:
  • --n number of reduction steps to run
  • --max-outputs number of inputs/results to display
  • --smt Pass "z3" or "cvc4" to select a solver [Default: Z3]
  • --time Set a timeout in seconds
